Schwelltöne / swell tones (?)

Exercise: From thin to thick / soft-loud-soft
Variations:
1. Jawning crocodile: stay on one note. start soft in thin folds and get louder with thicker folds.
2. Improvise a melody while doing the swell tone. Can you hear some notes that inspire you?

Info: Adjust the tubes depth to the loudness and pitch of the note. Soft notes = less water resistance
Loud notes = more water resistance (just minimal changes).
